Diagnose and Fix a Fast Blinker with a New Turn Signal Bulb
If you have a blinker or turn signal blinking fast, there is an easy solution that almost any car owner can do. You may need a screwdriver or ratchet to remove the screws from the tail light or all you may need is a pair of gloves. All you need to do is change the brake light bulb.
Check out the video below around 0:33 to see the comparison of a turn signal flashing fast and a turn sign flashing at a normal rate.
How to Tell a Turn Signal or Blinker is Flashing Fast
A fast blinking blinker is rapid and there will be no working tail light for that side. The hazard lights and brake lights will also not work. This means the brake light bulb needs to be replaced.
A working blinker should tick consistently about every second.
Why Is My Turn Signal Flashing Fast?
The turn signal or blinker is blinking fast because the brake light bulb for that side is burned out. If the brake light bulb is not burned out, there is probably an electrical problem with the indicator stalk switch.
